First Report of Ramularia Leaf Spot Caused by Ramularia collo-cygni on Leaves and Seeds of Barley in Estonia

Original language description

Ramularia leaf spot (RLS) is a disease of barley (Hordeum vulgare) caused by the fungus Ramularia collo-cygni Sutton & Waller (Rcc). Rcc causes necrotic lesions, premature senescence of leaves, and yield reduction. In 2009, 2010, and 2012, symptoms similar to those of RLS were observed on leaves of spring and winter barley in several Estonian agricultural regions. All samples were collected from untreated plots and leaves were observed under a dissecting microscope, revealing white clusters of conidiophores in rows on the undersides of the leaves. The fungus was initially identified as Rcc on the basis of morphological characteristics. To confirm the presence of Rcc, DNA was extracted from the original barley leaf material, milled seeds, and positive control mycelia of Rcc. Qualitative detection analyzed by standard PCR with primers RC3 and RC5 revealed the presence of Rcc in symptomatic leaves and seeds. To our knowledge, this is the first confirmed report of Ramularia leaf spot caused by Ramularia collo-cygni on barley in Estonia.
